srEcIFIoA'rIoN forming part of Letters latent No. 734,491, dated July21. 1903-. Application filed February 1, 1902. Serial No. 92,168. (llomodel.)

To all whom it may concern:

Be it known that I, FRANK BRADY, a citizen of the United States ofAmerica, residing at Denver, in the county of Arapahoe and State ofColorado, have invented certain new and useful Improvements inRailway-Velocipedes; and I do declare the following to be a full, clear,and exact description of the in-' vention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the figures ofreference marked thereon, which form a part of this specification.

My invention relates to improvements in railWay-velocipes; andit-consistsof the features, arrangements, and combinations hereinafterdescribed and claimed, all of which will be fully understood byreference to the accompanying drawings, in which is illustrated anembodiment thereof.

In the drawings, Figure lis a perspective view illustrating thepreferred form of my improved machine. Fig. 2 is a top view of the frontwheel'or the wheel directly in front of the rear wheel of the tricycle,showing its connections. Fig. 3 is a similar View of the third Wheel orthe wheel occupying the opposite rail from that engaged by the frontwheel. Fig. 4 illustrates a joint in the front axlebar. Fig. 5 is asection taken through the rear frame-bar and the hub of the rear wheel.Fig. 6 illustrates in detail a clamp for connecting the crank-shaft withthe main framebar, the same being shown in two positions and on asmaller scale than in Fig. 9. Fig. 7 shows in detail the fulcrum of thehand- Fig. 8 is a perspective view of a four-wheeled machine embodyingmy improvements, except the folding features which are peculiar to thetricycle form of the machine. Fig. 9 is a detail View of thecrank-hanger construction. Fig. 10 illustrates the hand propellingdevices, the pitman being shown in two positions, one connected and theotherdetachedfrom the pedalcrank. I

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate a longitudinal frame for connecting thefront and rear transverse bars 6 and 7, respectively, which are rigidlyconnected with the bar 5. An up right bar-8 is also rigidly connectedwith the bar 5. The saddle 9 is connected with the upper extremity ofthe bar 8. V I

Journaled-in the rear frame-bar 'l, which is tubular for the purpose, isa spindle 12, to which is made fast the rear wheel'lS, which isconstructed after the manner of a carwheel and flanged to hold it inplace on a railway-rail. Tothe inner extremity of this spindle or theextremity remote from the wheel 13 is made fast a small sprocket-wheel14, connectedby means of a chain -15with a larger sprocket-wheel l6,faston a crank-shaft 17, mounted on the frame-bar 5 by means of a bearin g18, clamped to the said'bar. The exn tremities of this shaft areprovided with pedalcranks 19 and 20. The crank-20 is provided at asuitable distance from the shaft with an offset forming a wrist-pin 20with which one extremity of a pitman 21 is connected The oppositeextremity of this pitman is connected with the lower arm of a hand-lever22,

fulcrumed on'the frame-bar 5, as shown at a cross-bar 22",, convenientlylocated and within easy reach of the hands of the rider while sitting onthe saddle 9; The foot-pedals and hand-lever may be used separately orconjointly, as may be desired. If itis not desired to use thehand-lever, thepitman 21 is detached from the crank 20 and connectedwith one extremity of a foot-rest 25, mounted on the frame-bar 5, asindicated by dotted lines in Figs. 1 and 10. If the rider does not wishto use the pedals, he places his feet on the foot-rest and operates themachine by the use of the hand-lever alone.

Forward of the frame-bar 6 and paralle therewith is a short axle 6, onwhich the for-, One extremity? of this class the tendency of the thirdwheel is to drag and cause the machine to run off the track. Theaforesaid adjustment ofthe forward wheel overcomes this tendency, andthis adjustment becomes practicable by providing a special axle for theforward wheel independently of the axle-bar upon which the third wheelis journaled. The framebar b is provided with a hinged extension 6, inthe outer extremity of which is inserted a stub-axle 26, on which thethird wheel 13 is journaled. The bar 6 is tubular, and the axle 26 isadjustable longitudinally therein to regulate the distance between thewheels 13 and 13 to correspond with the distance between thetrack-rails. The axle 26 is held in the adjusted position by a setbolt27. The hinge-joint 6 between the parts 6 and 6 is formed, as shown inthe drawings, by inserting a tongue formed on one part in a slot formedin the end of the other part and passing a bolt through registeringapertures formed on the engaging parts. This bolt forms a pivot or hingepin upon which the part 6 is allowed to turn, as hereinafter explained.Rigidly connected with the framebar 7 is a short bar 7, which extendstoward the wheel 13" or in a direction obliquely across the frame-bar 5.To the outer extremity of the bar 7 is hinged, as shown at 7 anextension-bar 7. As shown in the drawings, this joint 7 is substantiallythe same as shown in Fig. 4, and therefore need not be described more indetail. The extremity of the bar 7 remote from the hinge-joint isconnected with the outer extremity of the axle-bar 6 by means of aclamping-collar 28, passed around the axle-bar extremity and embracingthe extremity of the bar 7, which is connected with the collar by abolt, as shown at 29. A rigid brace-bar 30 extends from the bar 7 to theupper part of the bar 8. A frame-bar 31 connects the upper part of thebar 8 with the bar 7. The upper extremity of the bar 31 passes betweenthe members of a bifurcated lug fast on the bar 8 and is connectedtherewith by a bolt 32. The opposite extremity of the bar 31 isconnected by a bolt 34 with a clamping-collar 33, adjustable on the bar7.

When the machine is in use, the rider, seated on the saddle 9, works thepedal-cranks with his feet in the manner common to riders of tricyclesand other similar machines propelled by foot-power. The hand-lever atthe same time is moved back and forth, whereby the power of the handsand feet cooperate to propel the machine. If it is not desired to usethe hands, the pitman 21 is disconnected from the crank 20 and connectedwith the foot-rest, as aforesaid. This holds the lever 22 rigid or looksit against movement. Then the feet are not in use in propelling themachine, they are placed upon the foot-rest 25. lVhen the machine is notin use, it may be folded into small compass for shipment by removing thebolts 32 and 29. When the bolt 32 is removed, the upper extremity of thebar 31 is free, and the said bar may be moved downwardly to a positionparallel with the bar 7. When the bolt 29 is removed, the forwardextremity of the bar 7 is free, and the said bar may be moved toward thebar5 from the hinging-point 7 as a center. The axle-bar G and the wheel13 may then be swung rearwardly on the bolt 6 as a center until thewheel 13 engages the wheel 13, the two wheels in this case occupying aposition at right angles to each other.

In the construction shown in Fig. 4 there are four wheels (designated35) mounted on front and rear axles 36'and 37, respectively. The frontwheels are journaled on their axle, while the rear wheels are fast onthe axle 37, which is provided with small sprocket-wheels 3b,connectedby chains 39 with large sprocketwheels 40, mounted on crank-shafts,substantially in the same manner as shown in Fig. 9 and heretoforeexplained in detail. The front axle 36 is connected with two shortframe-bars 41 in the rear by longitudinal bars 42, upon which thefoot'rest 43 as Well as the crank-shafts are mounted. There are twohand-levers 44 connected and operated substantially as heretoforedescribed when speaking of the hand-lever 22 in the other form ofconstruction. The four-wheeled machine as shown in the drawings isconstructed to accommodate two riders, there being two saddles and twosets of propelling mechanism. It may, however, be constructed for asingle rider. This machine is operated the same as the tricycle, but isnot constructed to fold for shipment, as is the tricycle. Hence for asingle rider the tricycle is preferred.

Having thus described my invention, what I claim is- 1. In arailway-velocipede, the combination with a suitable frame, track-wheels,a pedal crankshaft, and means for transmitting motion from said shaft toone of the wheels of the machine, of a hand-lever fulcrumed on theframe, a pitman connected at one extremity with one arm of thehand-lever and detaehably connected with one of the pedalcranks, afoot-rest mounted on the frame and projecting into the plane of thepitman,whereby when the pitman is detached from the pedal-crank, it maybe connected with the foot-rest, thus locking the hand-lever againstmovement, substantially as described.

2. Ina railway-velocipede, the combination with the track-wheels, frontand rear axles for said wheels, and a longitudinal frame-bar connectingsaid axles, of a pedal crank-shaft mounted on said longitudinalframe-bar, a sprocket-wheel fast on said shaft, a chain c011- nectin gsaid sprocket-wheel with the sprocket on the spindle of the rear wheel,a hand-crank fulcrumed on thelongitudinal frame-bar, and projectingbelow the same, a pitman connected with the lower arm of said lever atone extremity and detachably connected with one of the pedal-cran ks atthe opposite extremity, a foot-rest fast on the said frame-bar forwardof the crank-shaft, and projecting into the plane of the pitman, wherebywhen vthe latter is detached from the pedal-crank, it may be thrownforward and attached to the foot-rest, thus locking the'hand-lever'against movement.

3. In a railway-tricycle, the combination.

with the track-wheels, of a triangular frame mounted on the Wheels, anupright bar mounted on said frame for supporting the saddle, a brace-bardetachably connected with the upright bar and pivotally connected withthe diagonal bar of the triangular frame, at its opposite extremity, thediagonal bar and the front axle-bar of the frame being detachablyconnected and jointed to permit the machine to fold, substantially asdescribed.

4:. In a railway-tricycle, the combination with the track-wheels, and aframe, including a'forward axle-bar upon which the third wheel isjournaled, and a separate axle-bar for the forward wheel, the framebeing slotted to receive the last-named axle-bar extremity and permitadjustment, and nutsapplied thereto for holding the separate axle-bar inthe' adjusted position, substantially as described.

5. In a railway-tricycle, the combination with the track-wheels, and aframe including a forward axle-bar for the third wheel, and a separateand distinct axle forthe forward wheel, said last-named axle beingadjustably connected with the frame, which-is slotted toreceive theseparate axle extremity, and means for holding the separate axle in theadjusted position, substantially as described.

6. In a railway-Velocipede, the combination with a suitable frame,track-wheels, a pedal crank-shaft and means for transmitting motion fromsaid shaft to one of the wheels of the machine, of a pedal-crank fast onsaid shaft and provided with an offset intermedi ate its extremities,ahand-leverfulcrnmed on the frame, and a pitman pivotally connected atone extremity with one arm of the handlever, its opposite extremitybeing detachably connected with the offset of the pedal-crank, afoot-rest fast on the frame forward of the crank-shaft, and projectinginto the plane of the pitman, whereby when the latter is detached fromthe pedal-crank, it may be thrown,

forward and attached to the foot-rest thus locking the hand-leveragainst movement,

substantially as described.
